COMPUTER-BASED MODEL OF PAVEMENT SURFACES

摘要

In order to facilitate the effective monitoring, testing, maintenance, and rehabilitation of pavement surfaces, a general model of pavement surface characteristics suitable for a wide range of applications is being developed. The surface model can include multiple types of sensor information, provides methods to integrate differing sensor data, incorporates multiple surface characteristics, supports automatic extraction of characteristics, provides different levels of surface model abstraction, and represents characteristics at different levels of spatial aggregation. With such a representation model, the development, implementation, and integration of improved sensors, management aids, and robot effectors could be considerably simplified. Although the primary applications of the model are to pavements, the model could be used for other constructed surfaces.
